At least on my Debian box there's a logkeys package available that might serve if you can maybe find a way to tail its output in an on-screen window during your presentation. Here's a fragment of example output it captured while I was composing this email with vi as launched from exmh:

Do other users need to be on the same system w/o restrictions? If not, I'd create a VM (or physical system if you have $$) with its own firewall and only that user. Block everything in/out except what's needed. Run only that app in there. If some sites are allowed, add a proxy to restrict

Very interesting, and additional information that I was not aware of, naturally. For a short while, maybe nine years ago, I had an office with an Alpha machine that was running OpenVMS 6.something, and then when my managers found out that it could run NT, they made me change it to NT. I wish now

dual pci nic with bridging

2010-08-17 Thread Brian St. Pierre
Anybody have experience with a PCI-based dual-interface NIC that does hardware bridging? This would be for a traffic monitoring application, so the host cpu must be able to snoop traffic. Software bridging is not feasible. Thanks for any pointers. -- Brian St. Pierre
